Is a engine wire harness in a 1997 Ford explorer compatible with the engine in a 1999 Ford explorer?

I own a 1997 Ford explorer. It has a 4.0L 16V SOHC engine. I need a engine wire harness. I wanted to take the harness out of my friends 1999 Ford explorer. Our car is basically the same model and make but just has a 2 year difference. Would the harness in the 1999 fit my 1997. His engine is also 4.0L 16V SOHC.|||call a ford dealer and ask the parts dept if they are the same part number if they are your fine if not do not use it.|||cant say for definite but i would say probably not
